About this study
the purpose of this study is to assess the effect of norepinephrine and fluid expansion on capillary refill time during septic shock.
Read the detailed description
An interventional study compared, in septic shock, the effect of resuscitation strategy targeting normalization of capillary refill time versus strategy targeting serum lactate level. This last highlight a decrease of organ dysfunction at 72 hours with capillary refill time strategy and non-significant trend towards lower 28-day mortality in the capillary refill time strategy group.
The strategy guided by the decreasing of capillary refill time allowed the administration of less fluid than that guided by lactate. This is an important advantage when the intensive care doctor know that the mortality of patient in septic shock increases with the amount of fluid administered.
However, the variations of capillary refill time induced by the principal treatment in septic shock (norepinephrine and fluid resuscitation) during circulatory failure are actually insufficiently described. The purpose of this study is to assess the effect of norepinephrine and fluid expansion on capillary refill time during septic shock.

What is being measured
The primary outcome is the main question the study is designed to answer.
Difference of capillary refill time before and after the therapeutic change
Capillary refill time (CRT) is time required for return of color after application of blanching pressure to a distal capillary bed. In this study, we made a calibrated compression of the skin using a piston for seven seconds, and we recorded CRT with a smartphone's video camera.
Measured: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
Secondary outcomes (3)
Correlation between capillary refill time and perfusion index
Capillary refill time is time required for return of color after application of blanching pressure to a distal capillary bed. In this study, we made a calibrated compression of the skin using a piston for seven seconds, and we recorded CRT with a smartphone's video camera.
Measured: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
Least significant change of capillary refill time
Capillary refill time is time required for return of color after application of blanching pressure to a distal capillary bed. In this study, we made a calibrated compression of the skin using a piston for seven seconds, and we recorded CRT with a smartphone's video camera.
Measured: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
Difference between capillary refill time on thorax and on the index finger tip
Capillary refill time is time required for return of color after application of blanching pressure to a distal capillary bed. In this study, we made a calibrated compression of the skin using a piston for seven seconds, and we recorded CRT with a smartphone's video camera
Measured: Change from capillary refill time between the 15 min before the therapeutic, Immediately after fluid administration and within the 15 minutes of a change in norepinephrine dose
